In the event of fire, the effectof the heat will cause the fiber washer 17 and the fiber wedge '18 toburnout or become disintegrated, thereby releasing the metal bearingblock and thus preventing bindin of the door when thent-he metal partsof the door or door guides expand due to the heat of the fire.

It is noted that any desired number of guide shoes may be secured to theside rail of the door, two shoes being ordinarily used on each side ofthe door.

The hereinbefore described arrangement admits of considerablemodification, and I do not wish to be limited to the precisearrangements shown and described.

What- I claim is:

1. The combination with a frame member and a sliding closure membertherefor, of a guide for the sliding closure member, said guide beingsecured to one of said members in position to cooperate with theadjacent edge of the other of said members, a bearing block mounted onsaid guide bet-ween the op posing faces of said members, and means foradjusting said block towards and away from said opposing faces to takeup wear and to obtain the desired play therebetween.

2. The combination with a frame member and a sliding closure membertherefor, of a guide for the sliding closure member, said guide beingsecured to one of said members in position to cooperate with theadjacent edge of the other of said members, a bearing block mounted onsaid guide between the opposing faces of said members, means foradjusting said block towards and away from said opposing faces to takeup wear and to obtain the desired p'lay therebetween, and means forsecuring said block in the desired position of adjustment.

3. The combination with a frame member and a sliding closure membertherefor, of a guide for the sliding closure member, said guide beingsecured to one of said members in position to cooperate with theadjacent edge of the other of said membens, a bearing block mounted onsa d guide between the opposing faces of said members, means foradjusting said block towards and away from said opposing faces to takeup wear and to obtain, the desired play tiherebet-ween.

means for securing said block in the desired position of adjustment, andmeans whereby the securing means for said bearing block is adapted to bereleased by exposure to fire.

4. The combination with a frame member and a sliding closure membertherefor, of a guide for the sliding closure member, said guide beingsecured to one of said members in position to cooperate with theadjacent edge of the other of said members, a bearing block mounted onsaid guide between the opposing faces of said members, means foradjusting said block towards and away from said opposing faces to takeup wear and to obtain the desired play thcrebelween, means for securingsaid block in the desired position of adjustment, and means whereby thesecuring means for said bearing block is adapted to be released byexposure to fire, said block adjusting means being combustib'le, wherebyit is adapted to become disintegrated by exposure to fire.

The combination with a frame member and a sliding closure mcn'ibcrtherefor, of a guide for the sliding closure memlua', said guide beingsecured to one of said mcn'ibers in position to cooperate with theadjacent edge of the other of said members, a bearing block mounted onsaid guide between the opposing faces of said members, and means foradjusting said block towards and away from said opposing faces to takeup wear and to obtain the desired play thcrcl ctwccn, said blockadjustingmeans being combustible. whereby it is adapted to becomedisintegrated by exposure to fire.

6. A guide shoe for vertically slidable lire doors comprising a bracketmember adapted to be secured to the side edge of-the door and havingspaced guide flanges adapted to straddle a guide rail for said door, a.bearing block supported between said guide flanges for sliding movementtowards and away from said guide rail, and a wedge for forcing saidblock in the direction of said guide rail.

7. A guide shoe for vertically slidable lire eoors comprising a bracketmember adapted to be mounted between the side edge of the door and aguide rail for said door, a hearing block mounted on said bracket memberfor sliding movement towards and. away from said guide rail, and a wedgefor forcing said block in the direction of said guide rail. 7

8. A guide shoe for vertically slidable fire doors comprising a bracketmember adapted to be secured to the side edge of the door and havingspaced guide flanges adapted to straddle a guide rail for said door. abearing block supported between said, guide flanges for sliding movementtowards and away from said guide rail, a wedge for forcing said block inthe direction of said guide angle, and means for locking said block inthe desired adjusted position.

A guide shoefor vertically slidable fire doors comprising a bracketmember adapted to be secured to the side edge of the door and havingspaced guide flanges adapted to straddle a guide rail for said door, abearing block supported between said guide flanges for sliding movementtowards and away from said guide rail, a wedge for fore ing said blockin the direction of said guide angle, and means for locking said wedgein the desired adjusted positioln 10. A guide shoe for verticallyslidable tire doors comprising a bracket member adapted to be secured tothe side edge of the door and having spaced guide flanges adapt ed tostraddle a guide rail for said door, and bearing block supported betweensaid guide flanges for sliding movement towards and away from said guiderail, a wedge for forc ing said block in the direction of said guideangle, means for locking said block in the desired adjusted position,and means where by the securing means for said bearing block is adaptedto be released by exposure to fire.

11. A guide shoe for vertically slidable lire doors comprising abracket: member adapted to be secured to the side edge of the door andhaving spaced guide flanges adapted to straddle a guide rail for saiddoor, and bearing block supported between said guide flanges for slidingmovement towards and away from said guide rail, a wedge for forc ingsaid block in the direction of said guide angle, means for locking saidblock in the desired adjusted position, and means whereby the securingmeans for said bearing block is adapted to be released by exposure tofire, said wedge being combustible, whereby it is adapted to becomedisintegrated when ex posed to the action of fire.

12. A guide shoe for vertically slidable fire doors comprising a bracketmember adapted to be secured to the side edge of the door and havingspaced vertical guide flanges adapted to straddle a guide rail for saiddoor, a bearing block disposed between said guide flanges with one edgein coopera tive relation to said guide rail, a bolt extending throughsaid bearing block and said flanges for clamping said block between saidflanges, said flanges being provided with horizontal slots adapted toslidably support said bolt, a nut on said bolt, a combustible washerbetween said nut and the flange adj acent thereto, a combustible wedgeextending between said flanges in position to engage said bearing blockto force the same in the direction of the guide rail, and an ad justingscrew mounted on said guide shoe in position to move said wedge intoengagement with said block.
